在无人机赋能千行百业的进程中，其伴生的低空安全问题已成为不容忽视的现实挑战。现有的无人机防控体系可以有效应对常规消费级无人机威胁，但是难以应对网联无人机这一新型威胁。通过论述现有无人机防控技术优缺点，分析发现现有防控技术与装备难以有效探测和反制网联无人机。研究面向网联无人机的低空安全防控应对策略与技术方案，通过地理和通信信息融合建模、多模态侦测预警、电子围栏自动生成、感通导控一体化芯片、应急处置预案智能生成、空天地一体化监测网、智慧指挥控制系统、便携式执法终端等策略，防范化解网联无人机带来的低空安全风险，推动以高水平低空安全护航低空经济高质量发展。

As Unmanned Aerial Vehicles(UAVs) continue to empower a broad spectrum of industries, the associated challenges of low-altitude security have become an increasingly pressing concern.Existing UAVs countermeasure systems are generally effective in dealing with conventional consumer-grade drone threats but struggle to address the new and complex risks posed by net-linked UAVs.The current development and challenges of UAVs are reviewed, and the strategic importance of net-linked UAVs is emphasized.The advantages and limitations of current counter-UAV technologies are systematically evaluated, and their ineffectiveness in detecting and neutralizing net-linked UAVs are analyzed.A set of low-altitude security strategies and technical solutions tailored to the unique operational characteristics of net-linked UAVs are proposed, which includes geo-communication information fusion modeling, multimodal detection and early warning, automatic geofence generation, integrated perception-communication-navigation-control chips, intelligent generation of emergency response plans, space-air-ground integrated surveillance networks, intelligent command and control systems, and portable law enforcement terminals.Collectively, these measures can mitigate the security risks posed by net-linked UAVs and provide robust support for safeguarding the high-quality development of low-altitude economy through an advanced low-altitude security framework.
